Windows has some serious chug! Once I load up a game or whatever it's fine but it could take me 15mins to get that far with no exaggeration. Before I burn it and reinstall windows do we have any decent diagnostics tools I should try? So can't be arsed with the reinstall!

Done CCleaner, Panda found no malware or virus and I've been all up in dem guts of startup and task manager but no thing seems wrong.
